Abstract (en)
[origin: WO2018015201A1] A discharge head (30) of a liquid dispenser (10) with a pump device or accumulator for discharging liquid in the form of an atomised spray or in the form of a non-atomised liquid stream or in the form of individual droplets is known. The discharge head (30) is provided for fastening to a base unit (20) of the liquid dispenser (10), which base unit comprises a liquid reservoir (22). It has a housing (32), which is designed for stationary or linearly movable or linearly and rotatably movable fastening to the base unit (20) of the liquid dispenser (10). The discharge head (30) has a liquid outlet (34), through which liquid can be output from the liquid reservoir (22) into the surrounding atmosphere, and a liquid inlet (38), through which liquid can be conducted out of the liquid reservoir (22) to the liquid outlet (34). According to the invention, the liquid outlet (34) has an outlet duct (36) which passes through the housing. An internal part (50) is disposed inside this outlet duct (36); a spray opening (56) is provided at the end of a spray duct (54) on the end face (52) of the internal part which points in the direction of the surrounding atmosphere. The internal part (50) and the outlet duct (36) are displaceable relative to each other such that, in a first relative position, a bypass duct (64) is produced between an inner wall of the outlet duct (36) and an outer face of the internal part (50), the flow resistance of which is lower than that of the spray duct (54), and, in a second relative position, this bypass duct (64) is at least partially closed such that the flow resistance of the bypass duct (64) is greater than that of the spray duct (54).
